Single-pole household light
A 220 V household lighting loop with the live conductor routed through protection and control, plus a clear lower neutral return.
For the electrical installer
Scenario
An electrical installer needs a compact schematic for one wall switch controlling one ceiling lamp. The diagram should read like a real lighting circuit: supply at the left, fuse and switch on the live conductor, lamp at the right, and neutral returning below.
Annotation key
type=acsourcegives the 220 V mains source the AC symbol.F1andS1sit in series on the live path before the load.type=lampis explicit because a bareL1means an inductor in SPICE notation.live,protected, andswitcheddescribe electrical nets;0is the bonded neutral reference, not a coordinate.
How to read
Current leaves the source on live, passes through fuse F1 and switch S1, powers lamp L1, then returns on the bonded neutral reference 0. The auto-layout keeps that functional order left to right and draws the return as a lower rail instead of wrapping it around the top of the page.
